The Pittsburgh Steelers selected Ladygo with the 186th overall pick in the 16th round of the 1952 NFL draft.[6] In June, he signed a contract with the franchise.[7] He played three seasons for the Steelers from 1952 to 1954 as a right guard. In 1952, he played in twelve games and returned one kick for fouryards.[6] In August 1953, Ladygo was named among five "of the brightest names on the Steelers roster", who remained unsigned because they were dissatisfied with their contract offers. Owner Art Rooney, however, expected them to sign after the start of training camp.[8] Ladygo suffered a broken leg,[9] and did not see game action during the 1953 season.[6] In 1954, Ladygo returned to play in all twelve games.[6]
Ottawa Rough Riders
In 1955, he played for the Ottawa Rough Riders of the Canadian Football League. The Detroit Lions traded a future draft pick to obtain Ladygo's rights before the season,[10] but he stated that it did not change his plans to play in Canada.[11] He said, "I have not signed any contract with Pittsburgh and certainly not with Detroit. The Steelers exercised their option on me last May but I don't feel this entitles the club to my services. I want to play with Ottawa and intend to do so."[11] During the 1955 season, he returned one interception 12yards.[12] In September, the Ottawa Citizen "put down Pete Ladygo as the outstanding Ottawa lineman."[13] He recovered a fumble against the Hamilton Tiger-Cats, which was later converted into a score.[14] In an "improved" Ottawa squad's rematch against Hamilton, Ladygo, Joe Moss, and Avatus Stone played 55of the 60-minute game, and the Ottawa Citizen appraised that "they were all immense."[15]
After his season in Canada, Ladygo returned to Keyser, West Virginia, with his wife Jackie, where he worked as a teacher and football coach at Bruce High School in Westernport, Maryland, and as an assistant football coach at Potomac State.[11] He was inducted into the Potomac State College Athletic Hall of Fame in 1988.[16] He died in Keyser on August 22, 2014.[17]
